1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectivesPopulation-based studies on use of non-obstetric and obstetric surgical procedures during pregnancy are sparse. Therefore, our objective was to estimate the prevalence of surgery during pregnancy, including potential time trends, overall and by trimester and describe the characteristics of pregnant women undergoing surgery.

designThis study is a large nationwide cohort study.

settingFrom administrative and medical databases, we obtained information about all pregnancies ending in a live birth, a stillbirth or an abortion (spontaneous and induced) in Denmark during 1996-2015. Procedures (excluding caesarean sections) conducted during pregnancy were categorised as a non-obstetric or obstetric surgery and further divided into laparoscopic or non-laparoscopic procedures.

main outcome measureMain outcome measure is prevalence of surgery during pregnancy.

resultsWe included 1 687 176 pregnancies of which 108 502 (6.4%) received 117 424 surgical procedures. The prevalence of non-obstetric surgery was almost stable (1.5% in 1996-1999 to 1.6% in 2012-2015), whereas non-obstetric abdominal or gynaecological laparoscopic procedures increased from 0.5% to 0.8%. For appendectomies, the proportion of laparoscopic surgery increased from 4.2% to 79.2% during the study period. In 49 pregnancies, surgery for internal herniation was conducted in 2012-2015 versus none in 1996-1999. The prevalence of obstetric surgery, excluding invasive diagnostic tests, increased from 0.2% to 0.8%. High multiplicity, smoking, increasing age, body mass index (BMI) and parity were factors associated with a high prevalence of surgery during pregnancy.

conclusionsThe increase in the prevalence of laparoscopic surgery during pregnancy may reflect a decreased restraint concerning conductance of these surgical procedures during pregnancy. The increasing proportion of laparoscopic procedures complies with clinical recommendations, and the prevalence of surgery during pregnancy varied by multiplicity, smoking status, parity, age and BMI.
